PostCSS Focus

PostCSS(link is external) plugin to add :focus selector to every :hover
for keyboard accessibility.

See also postcss-pseudo-class-enter(link is external) for more explicit way.

*:focus {
  outline: 0;
}
.button:hover {
  background: red;
}

*:focus {
  outline: 0;
}
.button:hover, .button:focus {
  background: red;
}

If there is a :focus selector, it will be excluded from the processing.

.a:hover, .b:hover {
  outline: 0;
}
.b:focus {
  background: red;
}

.a:hover, .b:hover, .a:focus {
  outline: 0;
}
.b:focus {
  background: red;
}
